Features of the training process of freestyle wrestlers in the pre-competition stage

As a kind of sport, wrestling is characterized by a complex compositional nature of preparing, which requires equal attention to the development of the physical and functional qualities of an athlete. The aim of the study is to optimize the mode and algorithm of training loads of a competitive nature in the period of preparation. The effectiveness of the training process was evaluated by functional indices and blood lactate level not only at the end of training load, but also in the recovery period. In the process of the study also, pedagogical analysis was carried out, anthropometric parameters and analysis of body components were determined. The results of the study indicate the need for regular monitoring of the regime of loads in order to timely correction of the training process, taking into account the individual characteristics of wrestlers at the stage of pre-competition preparing. Keywords: competitive wrestling; freestyle wrestling; functional preparation; lactate; training process.

Outcome analysis of early surgery and conservative treatment in neonates and infants with severe hydronephrosis

Objective The treatment strategy and timing of ureteropelvic junction obstruction (UPJO) in infants remain controversial. This study aimed to compare the effect of early surgical treatment (EST) and conservative treatment (CT) on neonates and infants with UPJO and their recovery of renal function and morphology. Methods Eighty neonates and infants with severe hydronephrosis were enrolled in this study. They received early pyeloureteroplasty or CT. Diethylenetriamine pentaacetate was used to assess renal function. Results There were no significant differences in renal function or renal indices at baseline between the two groups. At 3 and 6 months of follow-up, the anteroposterior diameter of the renal pelvis and the Society of Fetal Urology grade in the EST surgery group were significantly lower compared with those at baseline. The thickness of the renal cortex was greater in the EST group than in the CT group at 3 and 6 months of follow-up. After follow-up for 6 months, renal function in the EST group was significantly better than that in the CT group. Conclusion EST accelerates the recovery of renal morphological and functional indices in neonates and infants with severe hydronephrosis.

Index evaluation of physical development of students

The article presents materials of a comparative study between index estimates of the physical development of students between two ethnic groups. Physical development is one of the most important indicators of the health not only for the young generation, but also for the whole population. The indices of physical development represent the ratios of individual anthropometric characteristics, which allows them to be used for a rough assessment of physical development in the course of mass surveys of the population, as well as for analyzing the influence of various environmental factors on the body. The study involved 336 girls aged 17 to 20 years studying at Kostanay State Pedagogical University. The studies were conducted in accordance with bioethical rules. All studies were conducted in inter-sessional period, in the first half of the day. Depending on nationality, the respondents were divided into two groups: the first group — students of Kazakh nationality, the second group — students of Slavic nationalities. The studied groups identified the main anthropometric (heihth, body weight, chest circumference), physiometric parameters (vital capacity of the lungs, hand strength, blood pressure), anthropometric (Quetelet, Pigne, Manouvrier) and functional indices (Robinson, Skibinsky, life and dynamometric indices). In the studied groups, significant differences were revealed in the main anthropometric indicators, the characteristics of the Manouvrier index, and the index of life. The revealed excess of the average group indicators of the girl students of the second group is due to the genetic predisposition of the morphological and functional characteristics of the organism.

EVALUATION OF EFFECTIVENESS OF SPIRIVA RESPIMAT FOR PATIENTS WITH OCCUPATIONAL COPD

Spiriva respimat proved to be an effective and safe medication for medical treatment of patients who suffer from moderately severe occupational COPD. Spiriva respimat has advantages of glycopyrronium bromide: functional indices (FEV1 forced expiratory volume during the first second), clinical data (dyspnea), quality of patients’ life, frequency of exacerbations, the period before the first exacerbation happens, and patient compliance.

Establishing of the mono- and polyinvasion impact on some morpho-functional indices in wild boars

In the paper is described the mono- and poly-invasions impact on some morpho-functional indices in wild boars. So, in result of the investigation of hematological indices in uninfested mono- and poly-parasitized wild boars, it was established that both the indices of hemoglobin content, of hematocrit, erythrocyte’s number, thrombosis time and ESR (erythrocyte sedimentation rate) vary and are more increased in the I group with uninfested wild boars compared to mono - and poly-parasitized ones. It has been established that at infested boars with S. papillosus from the I group, and in those infested with D. lanceolatum from the II group there is a decrease of hemostatic indices, but their maximum decrease is highlighted in the IV group with wild boars infested with Dicrocoelium lanceolatum, Strongyloides papillosus, Metastrongylus elongatus and Eimeria debliecki. This decrease is due to eliminated exotoxins by parasites, which contain anticoagulants and hemolyzers and which neutralize the fibrinogen, thrombin, Ca+ ions and vitamin K properties from the body.

Alterations in brain structure and function in patients with osteonecrosis of the femoral head: a multimodal MRI study

Background Pain, a major symptom of osteonecrosis of the femoral head (ONFH), is a complex sensory and emotional experience that presents therapeutic challenges. Pain can cause neuroplastic changes at the cortical level, leading to central sensitization and difficulties with curative treatments; however, whether changes in structural and functional plasticity occur in patients with ONFH remains unclear. Methods A total of 23 ONFH inpatients who did not undergo surgery (14 males, nine females; aged 55.61 ± 13.79 years) and 20 controls (12 males, eight females; aged 47.25 ± 19.35 years) were enrolled. Functional indices of the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo), and a structural index of tract-based spatial statistics (TBSS) were calculated for each participant. The probability distribution of fiber direction was determined according to the ALFF results. Results ONFH patients demonstrated increased ALFF in the bilateral dorsolateral superior frontal gyrus, right medial superior frontal gyrus, right middle frontal gyrus, and right supplementary motor area. In contrast, ONFH patients showed decreased ReHo in the left superior parietal gyrus and right inferior temporal gyrus. There were no significant differences in TBSS or probabilistic tractography. Conclusion These results indicate cerebral pain processing in ONFH patients. It is advantageous to use functional magnetic resonance imaging to better understand pain pathogenesis and identify new therapeutic targets in ONFH patients.

Application of ischemic preconditioning in the rehabilitation of miners suffered from the vibration disease

Introduction. Vibration disease is characterized by the early development of sensory polyneuropathy. Sensitive disorders significantly worsen the quality of life and increase the duration of the unemployable period of miners, which requires the search for new modern methods of correction and rehabilitation. Ischemic preconditioning is a promising direction in the treatment of occupationally caused polyneuropathies. However, its potential neuroprotective effect has not been sufficiently studied. The aim of the study was to evaluate the effectiveness of ischemic preconditioning of the upper extremities for the correction of sensory polyneuropathy manifestations in miners with vibration disease. Material and methods. Seventy-eight persons with a proven diagnosis of vibration disease were examined. According to a specially elaborated technique, the ischemic preconditioning of the upper extremities was performed in 46 patients who were included in the leading group; 32 patients made up the control group. The clinical and electroneuromyographic examination was carried out before the ischemic preconditioning procedure and on the 5th day of the study. Results. The initial clinical and neurophysiological indices in both groups did not differ statistically significant and indicated sensory polyneuropathy. After ischemic preconditioning, the subjects of the leading group showed an improvement in clinical and functional indices (reduction of numbness and paresthesia, improvement of vibration sensitivity, an increase in the sensory conduction velocity of impulse and the amplitudes of sensory responses) of the peripheral nerves of the upper extremities. In contrast, in the control group, there was no statistically significant change in objective indices. Conclusion. Ischemic preconditioning of the upper extremities is effective in the rehabilitation of miners with vibration disease, helps to reduce the manifestations of sensory polyneuropathy, sensitive disorders and normalize neurophysiological indices.

STUDY OF PHYSIOLOGICAL AND PSYCHOLOGICAL INDICES OF UNIVERSITY STUDENTS

Purpose: assessment of functional indices of external respiration, the level of physical health and the general state of the autonomic nervous system of university students. Material: There were examined 192 students aged 18-21 years. All examined were divided into groups depending on gender, age and future profession. Anthropometric indices and parameters of the circulatory system were studied. Spirometer was used to measure the respiratory system functional indices. An express assessment of physical health level was made. Index of functional changes, the Kerdo vegetation index, the orthostatic index, and the Skibinskaya index were calculated. Stange test, Hench test and Martin-Kushelevsky’s test were conducted. Results: The results are showed that the minute blood volume was higher in all examined young girls, whereas in young boys designers and pharmacists aged 17-18 years and 19-21 years, respectively it was lower than due values. Similar data were obtained after the Ruffier test (dynamic load tolerance). The index of vital lung capacity (VC) was significantly lower than due values in all students. The parameters of maximal pulmonary ventilation indicated good functional ability of the external respiration apparatus in young boys. This index was higher than that of young girls and exceeded due values. The adaptation capacities of the student body (index of functional changes (IFI)) were at a satisfactory level. The indices of physical health level of all students had average values. Conclusions: Studies have revealed the most characteristic shifts of cardiorespiratory system indices, which are most expressed in students. Cardiorespiratory system shifts are caused by the influence of a complex of factors: increased academic load; requirements for the professionalization process continuity; performance of various structured activity types, manipulations, a high degree of responsibility. Increased pulse rate and minute blood volume; prevalence of the hyperkinetic type of blood circulation self-regulation at rest; irrational cardiovascular system response to dosed physical load; positive value of the Kerdo vegetation index; decreased ventilatory lung capacity and reserve capacity of cardiorespiratory system; tension of adaptation mechanisms; average level of physical health were recorded in students.

Functional and Taxonomic Diversity of Collembola as Complementary Tools to Assess Land Use Effects on Soils Biodiversity

Collembola have been proposed for several decades as a good model organisms to survey soil biodiversity; but most of the studies focused on taxonomic endpoints. The main objectives of this study are to compare the effects of the different land uses, including urban and industrial land uses, while using both collembolan functional and taxonomic biodiversity approaches. We collected data on 3,056 samples of Collembola communities across 758 sites in various land uses throughout France. The types of land use considered included all types of human activity from forestry to urban, industrial, traffic, mining and military areas, agricultural grassland, arable land, vineyards and urban vegetable gardens. In order to study functional and taxonomic biodiversity, we used community-weighted means, functional indices, species richness and density. When looking at collembolan functional diversity, urban and industrial soils appear clearly less diversified than when considering the taxonomic diversity. We suspect here a functional homogenization effect commonly reported in the literature for various organisms in urban ecosystems. Our study provides range of values for different taxonomic and functional indices of Collembola communities in a wide land use classification across France.
